Instructions for creating a free certificate from Let's Encrypt.

To begin with, we update the lists of packages and repositories of the system:

```
sudo apt-get -y update && sudo apt-get -y dist-upgrade
```

Installing **CertBot**:

```
sudo apt-get -y install certbot
```

Next, we install additional packages:

For **Nginx**:

```
sudo apt-get -y install python3-certbot-nginx
```

For **Apache2**:

```
sudo apt-get -y install python3-certbot-apache
```

## Certificate generation:

{% hint style="warning" %}
Please note that the **Web server** must be enabled!
{% endhint %}

For **Nginx**:

```
certbot certonly --nginx -d yoursite.com
```

For **Apache2**:

```
certbot certonly --apache -d yoursite.com
```

If you cannot enable the **Web server**, use the following command:

```
certbot certonly --standalone -d yoursite.com
```

We use the command to automatically issue an **SSL certificate**:

```
certbot renew
```

{% hint style="success" %}
Next, an automatic verification of the validity of your certificate will take place daily.
